Abstract

The aim of this study was to evaluate the alkaline hydrolysis of chemical composition of sugarcane bagasse from urban centers. The experimental design was completely randomized design in split plots (5×4), composed of five application levels (0, 1, 2, 3 and 4%) and four NaOH exposure periods (24, 48, 72 and 96 h) in four replicates. Dry matter, ash, neutral detergent fiber, acid detergent fiber, cellulose and lignin were analyzed. The application of 4% of NaOH promoted reduction of neutral detergent fiber (NDF) and acid detergent fiber (ADF). There was no significant difference (p> 0.05) in treatments with application of 3 and 4% of NaOH; the treatment promoted a higher reduction in hemicellulose content. There was linear effect of the level of NaOH on dry matter, ash, NDF, ADF, and hemicellulose, however, lignin and cellulose content presented quadratic effect. Alkaline hydrolysis with NaOH provided improvements in the chemical composition of the sugarcane bagasse, which allows it to be used as feed for ruminants raised in urban and peri-urban environments.

Key words: Chemical treatment, industrial waste, ruminant.
